The ATXMEGA256D3-MN is a Microchip AVR microcontroller in a compact 64-VFQFN package with exposed pad. It operates at 32MHz with 256KB flash and 16KB SRAM, from 1.6V to 3.6V. The device includes PWM, POR, BOD, and WDT, making it suitable for space-constrained and thermally demanding applications.

  • Space Saving: VFQFN package is smaller than TQFP.
  • Thermal Efficiency: Exposed pad aids heat sinking.
  • High Performance: 32MHz AVR core.
  • Large Memory: 256KB flash and 16KB SRAM.
  • Industrial Grade: -40°C to 105°C operation.
